Using current QEMU's default of 40 may limit the amount of RAM the guest can see (which is the reason why, in our packages, we bump that to 42; and as far as I've understood from reading some old mailing list threads on the subject, other downstreams do something similar).
In RHEL we provide custom machine types which set host-phys-bits=on by default, which is why making it configurable in libvirt hasn't been a high priority previously.
Yeah, and as I said, we bump that 40 to 42 in our QEMU package. I guess this is why not many people have bumped into this on our side either. Until now that I bumped into it... So, sad to admit, but apparently 42 was not the answer in this case. :-P Thanks and Regards -- Dario Faggioli, Ph.D http://about.me/dario.faggioli Virtualization Software Engineer SUSE Labs, SUSE https://www.suse.com/ ------------------------------------------------------------------- <<This happens because _I_ choose it to happen!>> (Raistlin Majere)
